To all whom it may concern: 7 l

salts-a Be it known that I. .lAYNARD H. .-\l.-

nnuxa-z, a citizen of the United States, residing at llattsburg, in the county of Clinton and State of New York, have inwmted certam new and useful lunn'oveinents in i Cushioncd -Vehlclc-'heels; and I do declare the'following to be a full, clear, and

' exact description of the invention, such as his will enable others skilled in the art to which it appertains to make and use the same.

1 :This invention relates to improvements in cushioned vehicle wheeis.

()ne object of the invention is to provide a wheel of this'character having arranged therein a )nculnat c cushion 'lllt'ltWlll provide all t to advantages of the usual pnen matic tu'e without-danger of heul'g puncturcd.

Another object is to provide a cushion wheel in which each spoke is a unit initself and works independently of the other spokes.

'ith the foregoing and other objects in view, the invention consists of certain novel features of construction,combination and arrangement of paz'ts as. will be more fully described and particularly pointed out in the appended claims. I

y In the accompanying drawings, Figure 1 is a side-' view of'a wheel constructed in accordance with the invention; Fig. 2 is a vert calcross section of the same taken on a line with two-of the spokes, the outer rinr being shown-as ofa slightly different-form;

Fig. .1 is a similar viewon the line 33 of Fig. 1; Fig. 4 is a central'verticai sectional view of a POPtlOILOf the wheel on the line 4- 1 of Fig. 2; Fig. 5 is a detail horizontal sectional view on the line 5-5 of Fig. 2; Fig. 6 is a plan view of a portion of the outer sectional rim of the wheel showing the manner in which the ends of the rim sections are shdahly connected together.

Referring more particularly to the drawings, denotes the hub of the wheel which is divided transversely to form two sections which are clamped together by clamping bolts :2 as shown. The'hnb is provided with a suitable bearing box 3, which is herein shown as formed-in one piece. On each end of the hub is arranged an annular plate 4, said plates being secured to the hub by the clamping bolts 2. The plates 4 are provided around their outer edges withannular offset: flanges 5, and the outer edges of the hub F rmf'rtrsiatiliofnnwlxoim tsection are provided \vitli 'iirinlilar (i, which cooperate with t-lie (itfset;

sockets 22 in which are screwed {the inner threaded ends of the spokes 14. On the opposite sides of the seats "21 midway between their ends are c is formed laterally projecting guide lugs. 23, which are adapted to be engaged with vertically disposed guide grooves 24 formed in the inner sides of annular guide. rings 25 'which are arranged on the inner sides of the 1 spokes 10 between the huband the rim 7 as s own. The rings 25 are secured. to the spokes by screws 26 or other suitable fas'tening devices. The rings 25 are preferably of skeleton form and serve to brace the spokes rooves 10 as well as to provide the guide 24 for the cushion s s 21. cured to the inner sideof the cushion seats 21 are pads 27, said pads being secured to the seats 21 by screws or other fastening devices as shown.

- The outer annular surface of the hub I is concave and engaged with said concave sur- ;face of the hub and arranged between the .same and the series of pads 27 and the cushion seats 21 is?! pneumatic cushioning tube 28, which 18 constructed snnllarly to apneamatic tire and is adapted to yieldingly hold the cushion spgokes 14 and the rim sections 15* carried there y in an operative position in the wheel. The cushion tube 28 is secured around its inner side'in an annular groove 2 formed in the outer concave surface of the By arranging the cushion spokes and forming the "outer rim in independent sections, each of which is connected to a sepa 'rate spoke, it will be seen that each Of'Sfild cushion spokes Wlll move independently of the other spokes as the wheel revolves and that any jars or shocks occasioned by the wheel passing over rough or uneven surfaces will be absor ed by the cushion tube28 with which the inner ends of the cushion spokes are engaged through the cushion seats secured to said inner ends of the spokes.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requirin a more extended explanation.

Various c anges inthe form, proportion.
